Dangerous thunderstorms will develop again on Tuesday across the Plains from Texas to the Dakotas. Violent storms could even reach as far east as Ohio and the Midwest.
Nearly 50 million people across the nation will have some risk for severe thunderstorms, including those in major cities like Chicago, Ill.; Indianapolis, Ind.; Detroit, Mich.; Kansas City, Mo.; St. Louis, Mo.; Cleveland, Ohio and Pittsburgh, Pa.
While the tornado threat will not be as great as some recent days, a few tornadoes cannot be ruled out, especially across western Nebraska, western Kansas and the Panhandles of Oklahoma and Texas.
The greatest impacts from Tuesday's severe weather look to come mainly in the form of very large hail and damaging thunderstorm wind gusts.
Hail could reach sizes as large as baseballs in western Nebraska, western Kansas and the Oklahoma and Texas panhandles.
This kind of hail is capable of causing serious injury to anyone caught outside. It can also kill exposed livestock, damage or destroy crops and smash windshields.
Elsewhere, hail larger than quarters is possible from Missouri into Illinois and eastward to perhaps Pittsburgh and Erie in Pennsylvania.
Hail of this size is still capable of damaging or denting vehicles and causing injury to people or animals that are exposed.
Winds gusts greater than 60 mph are possible throughout the threat region, and this kind of wind could easily topple trees, power poles and lift any unsecured objects.
These thunderstorms will also impact some of the same areas that were affected in recent days, and flash flooding from heavy rainfall will also be a concern, especially across parts of Nebraska, Iowa and Illinois.
If you will be out and about on Tuesday, keep an eye to the sky, especially in the afternoon and evening hours.
Once thunderstorms develop, they will strengthen quickly, and severe weather will likely follow soon after.
Be sure to understand the difference between a watch and a warning. A watch means that an area is being monitored for dangerous weather. A warning means that dangerous weather is imminent.
Keep in mind that lightning is one of Mother Nature's most dangerous killers. If you can hear thunder, you are close enough to the storm to be struck by lightning, even if the sun is still shining.
